Hello all and happy new year,

Today I had a surprise that graph was showing no lines except dots of the cursor for the series line.
I initialize with SciChartSurface.SetLicenseKey(“key here”); I have tried to create the SciChartLicence.xml and this way works.

annex is the example project. just set a correct key and you will have that behaviour.

Ok I investigated this, and to my relief, there is no problem – please call SciChartSurface.SetLicenseKey(key) before any SciChartSurface instance is shown (e.g. before InitializeComponent in MainWindow.cs). The best place to do this is in the constructor of App.xaml.cs, e.g.

Hello, please don’t post license keys in the public forum. I have modified your key so that it is invalid. If you are experiencing problems with licensing, please contact support [at] scichart [dot] com. Best regards, Andrew
